NASHVILLE, Tenn. (AP) — A grand jury has indicted a man and his girlfriend on murder charges in the shooting deaths of a woman and three teenagers in what prosecutors called a robbery during a pot deal in Tennessee.

On Friday, a Cumberland County grand jury indicted 26-year-old Jacob Allen Bennett and 25-year-old Lina Yvonn Moser on four felony murder and two attempted aggravated robbery charges. Bennett, who is accused of being the gunman, was also charged with four counts of premeditated murder.

Bennett and Moser are accused of trying to rob two of the victims during what the Tennessee Bureau of Investigation described as a marijuana exchange. Information about whether they had an attorney was not immediately available.
